Seawater Systems

Seacocks

SYSTEM DAMAGE HAZARD!
• Before using a seawater intake system, make sure that the system's seacock is in the OPEN
position before the system is started and keep the seacock open until the system is shut off.
• Close the seacocks whenever the systems will not be used for long periods of time.
A seacock is a valve, controlled by a 90º lever, used to manage
the intake of seawater through the hull and below the water
line. Seacocks are typically used on your boat in the following
seawater intake systems:
• Marine head (toilet)
• Air conditioning system (if equipped)
Before using any of these systems, make sure that the system's
seacock is open and remains open until the system is shut off.

Seawater Strainers

• Seawater strainers are used in water pickup systems to filter incoming seawater.
• A seawater strainer is located near each system's seacock.
• Check the strainers for leaks and/or debris every time you use your boat.
• If debris is found, clean the seawater strainer as follows:
FLOODING HAZARD!
• The seacock that sends seawater to the strainer must be CLOSED before disassembling
the seawater strainer to prevent the boat from taking on water through the seawater
strainer assembly.
• Keep the seacock CLOSED until the seawater strainer is completely reassembled.
SYSTEM DAMAGE HAZARD!
• After reassembling the seawater strainer, make sure that the seacock valve is OPEN before
using the component/system.
1. Make sure the component/system (air conditioning system, etc.) that the strainer is connected to is
turned off.
2. Close the seacock that sends seawater to the strainer you are about to clean. The seacock must remain closed until
the strainer is completely reassembled.
3. Take apart the seawater strainer.
4. Remove the debris.
5. Flush the strainer with water.
6. Reassemble the seawater strainer.
7. Open the seacock and check for leaks around the strainer. If no leaks are found, you may use the component
or system.
